Specifically formulated to operate flawlessly under intense environmental conditions with a specialized continuous maximum thermal rating of 150 degrees C (LL39 specification), this cable features four solid bare copper conductors, premium high-temperature fluoropolymer insulation, and a low-smoke, flame-retardant fluoropolymer outer jacket.\u003c\/p\u003e\n\u003cp\u003eThis specialized light-to-medium gauge profile is explicitly certified and approved for use within New York City's demanding high-rise building codes (NEC Article 760 and Local Law 39 parameters). It balances system-critical reliability with exceptional layout flexibility. Because it is unshielded, it features a smaller outer diameter and lighter weight profile, making it highly efficient for multi-zone notification systems, system status annunciators, and low-voltage auxiliary control circuits where external electromagnetic interference is not a concern. It can be installed directly in environmental air plenums, air-handling ducts, drop ceilings, and open architectural vertical shafts without requiring protective metallic conduit.\u003c\/p\u003e\n\u003ch3\u003eCABLE AMPACITY \u0026amp; SIGNALING DATA\u003c\/h3\u003e\n\u003cp\u003eBecause fire alarm systems operate under specialized power-limited and life-safety signaling profiles, standard high-current electrical ampacity charts do not apply directly to standard branch operations.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eMaximum Signaling Current Capacity: 5.0 AMPS (Per Conductor)\u003c\/b\u003e This represents the maximum safe continuous current limit for an 18 AWG multi-conductor fire alarm configuration under standard ambient facility conditions.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eNational Electrical Code Restrictions:\u003c\/b\u003e FPLP fire alarm loops must be supplied by a power-limited fire alarm (PLFA) transformer or signaling panel circuit breaker.
